CHARLES K. YOUNG, OF PHILADELPHIA, PENNSYLVANIA.

CAR-BAISER AND SAFETY-BRAKE.

To all whom t may concern:

Be it known that I, CHARLES K. YOUNG, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inCar-Baisers and Safety-Brakes, of which the following is aspeciiication, reference being had to the accompanying drawings.

rfhis invention relates to railway cars and the like, and moreparticularly to acar raiserl and safety brake for the same.

The objects of my invention are to provid-e a device which can bearranged to be used as a safety brake, and also as a car raiser when itshould be desirable to use it in either Way.

Further objects of my invention will become apparent as it is more fullyset forth.

It is well known that the ordinary type of brake used on street cars andrailway cars get out of order and will not work when they are mostneeded. By the use of this device a brake is provided, or a series ofbrakes whereby a positive brake action is brought into play andpositively actuates on the rails to impede the progress of the car, orbring it to a quick stop, when desired.

In the accompanying drawings which illustrate one form of my invention,Figure 1 represents a View in elevation of a car provided with a deviceembodying my invention; and Fig. 2 is a detail of a safety brake and carraiser embodying my invention partly in section.

Similar reference characters refer to similar parts throughout thedrawings.

In the construction illustrated by way of example in the appendeddrawings 1 represents a car which has mounted thereon a car raiser 2 ateach corner of the car, preferably in front of the wheels at each endand are disposed as to be directly over the rails on which the carwheels run. The safety brake is composed of racks 3 and 3 which haveplates 4f and 4L on the undersides of them, and are arranged toreciprocate in casings 5 and 5 which are secured to the underside of thecar. In order to actuate the racks, a pair of gears 6 and 6 are mountedso as to engage with the teeth of the racks and are suitably supportedat each end of a shaft 7 which is journaled to the bottom of the car andhas a beveled gear 8 so disposed on it as to be engaged and actuated bya beveled gear 9 which is mounted Specification of Letters Patent.

on a shaft 10 suitably supported by the car by a hanger 11.

Mounted on the staff 14 is a ratchet wheel 12 which is arranged to beengaged by a pawl 13, and to the staff 14: is secured a wheel or othersuitable actuating means arranged to be disposed at either end of thecar so as to be readily actuated by the motorman or conductor or thelike, in order to put the safety brake or car raisers in action.

In operation the operator actuates the handle or/ other suitable meansof the actuating mechanism 14 and thereby the transmission system, theshaft 10, the beveled gears 8 and 9, the shaft 7, and the gears 6 and 6,which actuate and propel the racks 3 and 3 downwardly, and on to therails which are disposed beneath the car, or on to the ground as thecase may be.

Then the plates have come in contact with the rails they of course exerta braking action on them, and tend to stop the car, this action will bevery powerful.

Vhen it is desired to raise the car for repair or inspection purposesthev actuating mechanism 14 is simply operated sufficiently to raise thecar to a desired height off the ground, as the length of the racks 3 and3 are sufficient to be used for this purpose. It is of course understoodthat should it be desirable to raise only the racks at one end that thesame can be done, or in any case itv is desired to actuate both racksthe same can be done together, as each is independently actuated of theother.

When it is not required to use the devices they are simply actuated andreturned to their casings 5 and 5 so as to be out of the way andinconspicuous.

This device has many advantages, first, being comparatively light and ofsmall cost to manufacture and install, secondly, it has a very strongand positive braking action, and thirdly, it can be used as a car raiserand thereby -obviate the necessity of carrying jacks or the like in thecars for such purposes, in case of accidents. The use of the pawl 13,and its means of operation are too well known to need furtherdescription except that it may be actuated in any well known manner forpreventing the braking device from turning backwardly while it is beingput into use.

Obviously while I have described my device with but a pair of safetybrakes at either end of the ear, I anticipate the use of more or lessthan this number, in case the conditions arise that necessitate the useof more or less, and I anticipate the use of varied shapes of shoes orplates disposed at the bottom of the racks and do not Wish to be limitedto the particular shape or form shown in the drawings, and I do not Wishto be limited in this or in any other Way other-y wise than necessitatedby the prior `art as many modifications in the construction of myinvention may be made Without departing from the principles thereof.

Having thus described the invention what is claimed is:

In combination With a car, a car raiser and safety brake comprising apair of racks, a pair of casings for supporting said racks, platesdisposed on the ends of said racks, gears for actuating said racks, ashaft for supporting` said gears, a beveled gear disposed on said shaftfor actuating the same, another beveled gear for actuating said beveledgear, a shaft for the last mentioned beveled gear, and means foractuating said shaft.

In testimony whereof I hereunto aiiix my `signature in the presence oft-Wo Witnesses.
